I don't think its possible to recall the special dialog however it is possible to store the color picker to a view and recall that view;

group x + group y + group z Wait=follow
view "name of that view" / Screen =1-5 Wait=Go
Store preset 4.(which preset number?) Wait=follow

You need to call the macro a second time to store the preset and fill in a preset number.
